From cultural touchstone to technological influencer, Hubble has left its mark on Earth
Hubble science has rewritten astronomy textbooks as its discoveries continually provide deeper explanations of astronomical objects and unveil new phenomena. But science isn’t the only way Hubble has impacted our world. From image detectors that are now used in the fight against breast cancer to science images that are used in Hollywood blockbuster movies, Hubble is embedded in our everyday lives and pop culture.

Hubble has not only furthered our knowledge of the known universe, it's shocked the astronomical world with never-before-seen phenomena.
When Hubble was launched, no planets around other stars had been discovered, Pluto had only one known moon, and dark energy was not even a concept. With over three decades of observations, Hubble has changed humanity’s understanding of the universe. We now know that black holes exist at the center of almost all galaxies, Jupiter’s massive storm – the Great Red spot – is now shrinking, light can echo just like sound, and the universe is expanding at an accelerating rate. Learn about Hubble’s great discoveries, understand the basics behind Hubble’s scientific capabilities, and explore its incredible images of the cosmos.
